Do all molecules at the same temperature have the same average speed?

Now here is an unexpected fact: the average kinetic energies of molecules of any gas at the same temperature are equal (since KE = 3/2kT, the identity of the gas does not matter). So the average speed at which an atom or molecule moves depends on its mass.

How does the speed of the different molecules that make up the air depend on their masses?

The speed of an air molecule depends on its mass because if you have a heavy air molecule it is going to move slowly because of the effect of gravity and its weight. The light air molecule is not going to move faster because since it is lighter it does not get affected by gravity as much as the heavier molecule.

What is the average velocity of the air molecules in the room where you are right now?

For typical air at room conditions, the average molecule is moving at about 500 m/s (close to 1000 miles per hour). Note that the speed of sound is largely determined by how fast the molecules move between collisions, and not on how often they make collisions. This is because no energy is lost during the collisions.

What is the average velocity of air?

The average air velocity for the period (June 17–23) was 0.06 m/s for the unscreened Trombe wall and 0.04 m/s for the screened one. Screening influences air velocity in the gap reducing the stack effect and the air flow rates. The effect is higher with low wind conditions. Figure 5.43.

What is the velocity of compressed air?

Most compressed air system designers recommend using a velocity of about 20 fps (feet per second) when designing discharge and interconnecting piping systems. It should not exceed 30 fps. When designing the downstream process feed lines, designers recommend using 30 fps, not to exceed 50 fps.

What is velocity of flow?

The time average of the velocity of a fluid at a fixed point, over a somewhat arbitrary time interval T counted from some fixed time t0. For example, the mean velocity of the u component is. The time average of any other quantity can be defined in this manner.

What is flow velocity in turbine?

The blades for a reaction turbine are always so shaped that the tangential or whirling component of velocity at the outlet becomes zero . Usually the flow velocity (velocity perpendicular to the tangential direction) remains constant throughout, i.e. and is equal to that at the inlet to the draft tube.

What is the flow rate in dexterous per hour?


What is the flow rate in dextrous per hour?

50.31 mg/hr

How do you calculate ml per minute?

Answer: If we divide 25 drops per minute by 15 drops per millilitre, we get how many millilitres per minute = 1.67 ml/min. If we then divide 1000ml by 1.67 ml per minute we get 600 minutes. 600 minutes = 10 hours.

How many milliliters are in a hour?

60.00 milliliters

What is CC hour?

The cubic centimeters per hour unit number 1.00 cm3/h , cc/hr converts to 1 mL/h, one milliliter per hour. It is the EQUAL flow rate value of 1 milliliter per hour but in the cubic centimeters per hour flow rate unit alternative.

How do you convert mL to hours?
